What Happened: The Timeline
Founded to commercialize NASA fuel cell technology
High-profile launch with Fortune 500 customers, massive media coverage

Still unprofitable after 20 years, cumulative losses exceed $3B
Stock down 85% from peak, market cap fraction of total funding raised
Root Causes
Key Lessons Learned
1. Technology Cost Curves Must Converge
Bloom's fuel cells never achieved the cost reductions needed to compete with rapidly cheapening solar and batteries.
2. Subsidy Dependence Is Not a Business Model
Government incentives masked weak unit economics for over a decade.
3. 20 Years Without Profit Is a Signal
Chronic losses across two decades of operation indicated fundamental product-market fit issues.
